Today in human geo class we watched a video on population pyramids and how important they are. Demographic transition is when you take the age, gender, and trend that goes with it to see where a country will be in a few decades. For example it could be pre-industrial, industrial, or post-industrial. Industrial is when a country is making a lot of money, has a bountiful supply of good paying jobs, and the economy is booming. Countries that are just now industrializing are slowly increasing life expectancy. Rural living vs urban living has changed during the industrial revolution because the factories were in the city so people moved in order to get a good-paying job.
